Other Parts Discussed in Thread: UCC29002
Hello,
I am using the LM5032 in an interleaved flyback design.
The input voltage range is 50-137V.
The maximum output load is 150W.
The LM5032 is supplied with an independent 12V source connected to VDD and VCC.
I experience an uneven load share over the two power paths. In the lower voltage area the load is supplied mainly via the OUT2 channel. In the mid range the load share is almost even while at 100V the main load is supplied over OUT1. The following picture shows the gate voltage at 50V input voltage and 150W load.
Can you suggest me any measures to ensure an even load share? For more details please contact me.
Thank you
Best regards
Felix
